Let 'em pick produce in the fields. In all seriousness this will ultimately reduce the illegal immigrant population, result in these "captive" employees paying their way.
Additionally I think this should be societal de rigueur for all nonviolent prisoners. They could pick produce while earning their keep. Chain gangs are what's needed here. Keep the highways clean of trash. Pick lettuce, tomatoes, etc.
Prison time should not be free time. Just because you did a crime doesn't mean its TV and weight lifting time. Earn your keep. And should Convenient Niggah Benny-Boy (a Filipinoish play on words
) whine about how there are more of his "people", his "brothas", in the Pinstripe Crib, well, suffice to say that means we need to arrest more caucasionals and other peeps of color to make it all better for him.
And feed the lot of 'em salt peter. That should keep them calm and easily controlled.
All violent prisoners should be put into tiny cells and left there. They can handle it. Just look at domestic pets such as birds. They live in cages just fine and they're a shitload smarter than any criminal human you can name.
